Sort of slow reading period

I'm still working on Lord of the World, but haven't gotten too much farther into it - I'm still only about 1/3 of the way through it. It's been a busy several days and I found that another book I had checked out is due soon and someone else had reserved it so I couldn't renew it. It was book 4 in a series and I needed to read book 3 first (this was checked out already when I found book 4). I decided to quick add these first so I didn't have to bring them home again.

First I read, Theodosia and the Eyes of Horus by R. L. La Fevers. Theodosia is a young girl who can see/feel the ancient Egyptian curses attached to the artifacts that come into her parents' museum, and she removes them. In the process she has met with a few groups of people who know about the artifacts and the reality of their power. One group hides these away, a second wants to use them to bring chaos to the world, and a third is harder to describe - something of a religion and she turns out the be the goddess for it - they're a bit weird. In this one she (along with her brother) find a green tablet that although the group that hides artifacts away for safekeeping says it's worthless and harmless, lots of people - some from the other two groups and another for whom she doesn't know quite the motives - seem willing to do anything to get their hands on it. This was quite entertaining - as were the first two in the series. Sadly for a good part of the first third to half of the book I wasn't quite sure if I'd read it already or not. Parts of it were quite familiar, but the farther in I got the less sure I got that I had already read it - by the end I knew I hadn't.

Book four in the series is Theodosia and the Last Pharoah. In this book Theodosia travels to Egypt with her Mother to learn more about her past, help on-site with an excavation she's already researched a bit, and to (secretly) return the green tablet from the previous book. She learns much - and seems to stumble into new dig sites. This book left me a bit uncertain as to whether there will be more in the series or not. I would like there to be; there is definitely more that could happen and more about her life we could learn (she is only 11 - almost 12 at the moment), but it almost felt as if this were the end. I guess I'll have to wait and see.
